Total Order Broadcast
本記事はdev.toから移植しました.
What is Total order? The way to determine if a given element is in total order is simple. That is, “Can you put those elements in a row?”.
For example, what if the natural numbers 7, 8, 1, 4, and 5 are given? We can then serialize 1<4<5<7<8. In other words, the natural numbers are total order.
What about the sets {b, d}, {d,d} {z, b} next? They cannot be serialized.
